Title: Structure of vibration unit in ink jet head
Inventor: KANEMATSU TOSHIHIRO
IPC: B41J2/14
Filed: 1988-02-09
Abstract: PURPOSE:To avoid the occurrence of vibration of a support board in a vibration unit, by a method wherein the vibration unit of chevron-shape is disposed upward of a diaphragm. CONSTITUTION:A vibration unit 1 is disposed above a diaphragm 5, and the vibration unit 1 is brought into contact with the diaphragm 5 at a chevron-shaped downward extending part 1b. With the application of an electric signal to an electrostrictive vibrator 2, the vibration unit 1 displaces the respective ends of the downward extending part 16 and an upward extending part 1c outwards about a part of a bent part 1a on which a support board 4 is mounted. At this time, the clockwise vibration of the downward extending part 16 allows the end part of the downward extending part 1b to press the diaphragm 5 downward, whereby an ink in a liquid chamber 8 is jetted out from a nozzle 9. When the downward extending part 16 displaces clockwise, the provision of the upward extending part 1c in the vibration unit 1 allows the upward extending part 1c to also simultaneously displace counterclockwise. This displacement of the upward extending part 1c acts against a force of the downward extending part 1b to be applied to the support board 4, therefore avoiding the vibration from occurring in the support board 4 accompanied with the jetting of the ink in the liquid chamber.

Title: Refrigerator
Inventor: AMAMIYA YUUJI
IPC: F25B1/00
Filed: 1978-03-09
Abstract: PURPOSE: To reduce the area of superheated gas in an evaporator for increasing the absorbing amount of heat and to ensure a stable refrigerating operation even in a frosted time by keeping the refrigerant in the equipped part of a thermo-sensing part in an expansion valve in a gas-state constantly to take a sufficient superheating degree of refrigerant.  
     CONSTITUTION: Refrigerant from a compressor 1 is condensed and liquefied in a condenser 2, and decompressed in an expansion valve 3. After passing through a liquid receiver 10 and a heating heat exchanger 9, it is decompressed in an expansion valve 3, and evaporated and gasified in an evaporator 4 to be sucked into the compressor 1. In this refrigeration cycle operation, a gas- issuing and oil-returning pipe 7 cannot take a sufficient superheating degree of refrigernat as it sucks liquid-refrigerant with oil through an oil-returning hole 6, but a gas-issuing pipe 8 can take a superheating degree of refrigerant of about 4 degrees C. for sure in the equipped part of a thermo-sensing part 3a as it does not suck liquid refrigerant. Consequently, the superheating degree of refrigerant is reduced to zero at the exit of the evaporator 4 by the heating effect of liquid-refrigernat of about 40 degrees C. running in the heat exchanger 9. Thus, the absence of a superheated gas area increases the area of heat-exchanging and the absorbing amount of heat, ensuring a stable operation even in a frosted time.

Title: Casing for acoustic transmission line speaker and method for synchronizing the same
Inventor: YI-FU YANG
IPC: H04R3/04
Filed: 1997-02-12
Abstract: PROBLEM TO BE SOLVED: To improve the confirmation of acoustic reproduction by providing a device and method for removing hollow resonance from a reproduced sound. SOLUTION: In a easing 10 of an acoustic transmission line speaker having a concentric cylindrical structural body, a sound wave 18 going backward and an air mass body surrounding it are connected acoustically. The specific rigidity or large flexing resistance of the cylindrical structural body enables the usage of an extremely thin cylinder, without increasing the capacity or size of the casing as a whole. Also, an acoustic amplifier which can synchronize with a listening room removes the extremely narrow low-frequency band of an acoustic signal. The flexing resonance of the listening room can be measured by detecting peak sound energy in the listening room and radiating the sound wave whose frequency is changing in the listening room. A filter removes the frequency related with the flexing resonance of the listening room from the acoustic signal.

Filed: 1989-02-07
Abstract: PURPOSE:To attain high quality transmission not susceptible to multiplex wave propagation by adopting a directivity control antenna for a mobile station antenna and directing the major radiation direction into the direct wave arrival direction so as to receive only a direct wave. CONSTITUTION:The system consists of antenna radiation elements 1, 2, feeding points 3, 4, a dielectric substance 5, a grounding conductor 6, phase shifters 7, 8 and a power distributer 9. Then the communication with a base station is implemented by controlling the exciting phase of the elements 1, 2 to direct the major radiation direction in the travelling direction as the mobile station approaches the base station and to direct the major radiation direction in the direction opposite to the travelling direction as the mobile station parts from the base station. Thus, the effect of multiplex wave propagation due to the reflection in the road face or in other vehicles is not susceptible, thereby improving the quality of transmission.
